Application filed May 26, 1915. Serial No. 30,623.

' To all whom it may concern Be it known that I, JAMES M. NIoHoLsoN, acitizen of the United States, residing at Chicago, in the county ofCook, State of Illinois, have invented certain new and usefulImprovements in Tripods; and I do hereby declare the following to` be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to supporting brackets or tripods for cameras.

It is my purpose to provide a supporting bracket for tripod particularlyadapted for use in connection with cameras of the folding or vest pockettype and through the instrumentality of which such camera can be readilysupported upon some convenient object, such as a tree for the purpose ofgaining the required steadiness in the operation of the camera,especially in cases where it is desired to indulge in a time exposure.

It is my further purpose to provide a device of the character namedwhich can be folded into a compact space to enable same to be carried inthe ordinary camera case.

N ith the above and other purposes in view the invention consists in thedetails of construction and in the arrangement and combination of partsto be hereinafter more fully described and particularly pointed out inthe appended claims.

In describing the invention in detail referencev will be had to theaccompanying drawings wherein like characters of reference denotecorresponding parts in the several views, and in which- Figure 1 is aperspective view showing a camera supported upon a tree through themedium of my improved bracket or tripod; Fig. 2. a view in elevation ofthe tripod detached; Fig. 3. a section on the line 3 3 of Fig. 2, andFig. 4. a fragment of what is shown in Fig. 2 partly in section.

Referring to the drawings my improved tripod is shown as comprising acentral arm A and terminal arms B and C. One end of the arm A is screwthreaded as at 10 while the other end thereof is provided with atransverse opening 11. Formed on the arm A are alined lateral extensions12 and 13, same being disposed relatively near the end of said armprovided with the opening 1l.

The outer ends of the extensions 12 and 13 are provided respectivelywith sockets 14 for a. purpose that will presently appear.

:Each of the arms B and C is formed of sections 15 and 16. Each section15 comprises an interiorly threaded tubular portion 17 and a solidportion 18 ydisposed at right angles to the tubular portion 17 andprovided on its outer end with a ball 19 operatively engaged in arelated socket 14. Each section 16 has one end threaded in the relatedportion 17 and its other end pointed as at 20. By this construction itwill be obvious that the arms A, B and C can be adjusted relatively toeach other throughout a wide range.

The tripod further embodies an arm 21 having one end provided with areduced threaded portion 22 and its other end bifurcated to form arms 23and 24. These arms have formed therein respectively alined openings 25and 26, the latter being threaded. The arms 23 and 24 embrace the arm Ain such manner that the openings 25 and 26 are disposed in line with theopening 11 and a thumb screw 27 is passed through these alined openingsand engaged with the threads of the opening 26 whereby the arm 21 may beclamped in any desired angular relation with respect to the arm A. Thethreaded portion 22 of the arm A is adapted to be detachably secured ina threaded opening 28 formed in the camera body, such camera beingindicated at D.

In the use of the tripod the arm 21 is iirst detached from the arm A andthreaded in the opening 28. The arm A is then screwed into thesupporting member a desired distance and the arms B and C engaged in thesupport beneath the arm A. The arm 21 is then secured to the arm A inthe desired angular relation and the tripod will then support the cameraas clearly shown in Fig. 1.

l/Vhat is claimed is 1. A tripod comprising a central arm having one endscrew threaded, alined lateral extensions on said arm adjacent the otherend thereof, said extensions being provided in their outer ends withsockets, terminal arms on each side of the central arm and havingangular extensions on corresponding ends thereof provided with ballsoperatively engaged in said sockets respectively, and an,

ing one end screw threadedfterininalarms" disposed respectively onopposite sides of the central arm and having a ball and socket"connection With the latter at one end, vthe end of the Central' arm adja'oent the ball and socket member being provided Withianopenl. ing, anarm having one end bifuroated and ernbr'aein'ggthelcentialE arm andhavingK open-1y ings in theffureatifon alining-'With the open#v ing 1nthe#centrall arm; ea thumb fsC-revv' f`en- Y gaged" througlil said"lali'ne'd.Vl openings and threaded inJ the 'opening in one ofsaidflfm--eations'-1wherfeby said-armi may-be secured 1nA adesireid-angular'relatioir with! respeot'l Sto the central arm, and means on the otherend ofsaid A.arm for securing the Camera.V

3. Atripod comprising a central arm havingL means at one end forengaging a supporting part, opposite integral alined lateral extensionson said arm adjacent the other end thereof, terminal arms on each sideof theoentral arm having a pivotal Connection Witli'one of saidextensions, and an arm adjustablypivotedqon the end of the central armadjacent said extensions and having means for oonneotingfsame-to acamera.
